Vakili et al. (2014) employed aromatherapy with lavender oil in an experimental model of stroke using four different experiments aimed at assessing the effects on: (1) infarct size; (2) brain edema; and (3) the presence of malondialdehyde (MDA; a biomarker of lipid per-oxidation and oxidative stress); and (4) the expression of Bcl-2 (an anti-apoptotic protein) and vascular endothelial growth factor (VEGF). The gene discussed is VEGFA; the disease is stroke disorder.
